but used the crappy bike lane that goes through the underpass as I don't think Vauxhall Cross is safe enough to cycle round at peak traffic. Too many people gunning for orange lights and changing lanes at the last minute.

I saw the person in question, near the lights leading on to Vauxhall Bridge, covered in red blanket, face down, being looked at by Ambo guys. Gut feeling was that it looked very bad to be honest - fingers crossed for a positive result.

Saw this from the train into Waterloo too (at about 08.30) - police car blocking / dirverting traffic in that lane and a fair number of cyclists looking on from the opposite pavement. Didn't see a cyclist or a bike but police were looking underneath the front wheels of the HGV.

Saw this as well. He seemed to be talking to medics when I passed, hope he's ok.
That junction is horrible. The fact that the bike lane under the underpass ends and you're in 4 lanes of buses is totally ridiculous.
